T all whom it may concern: j

Be it known that I, 2-; iLLniM S. GRAHAM, a j citizen of the UnitedStates, residing at Cani ton, in the county of Fulton and State ofIllinois, have invented certain new and useful Improvements in ofneeledPlows, of which the following is a specification, reference being had tothe accompanying drawings.

This invention relates to improvements in wheeled plows and has for oneof its objects to provide improved scans for raising and lowering theplow-beam whereby the plow bottom or plow proper will be so raised fromthe ground that it will be supported and held in substantially the samerelation to a horizontal line as it assumes when lowered into a workingposition, thereby insuring every part of the plows cutting edge beingheld sufficiently high above the ground to provide to and from theground to be plowed.

Other objects are to provide improved means for unlocking the rearwheel-axle to permit the caster-wheels carried thereby to swingsidewise; to provide improved means for changing the set or suction ofthe plow bottom to provide rigid carrying means for the rear wheelswhereby such wheels will be kept in alinement and a rigid structure as awhole be produced; and to improve generally machines of this class.

These objects I attain by the devices combinations of devicesillustrated in drawings and hereinafter specifically scribed.

That which I believe to be new will be set forth in the claims.

In the accompanying dra ;dngs,-Figures 1 and 2 are side elevations of myimpr ved machine, showing respectively the position of the parts whenthe plow bottom is lowered and raised. In both the figures theright-hand wheel is removed. Fig. 3 is a top or plan view of themachine. Figs. 4 and 5 are details, each being a side elevation of theplow-beam and the plow bottom carried thereby, shot.- ing also a portionof the mechanism employed for causing the raising of the plow bottom inthe required manner. A portion of one of the side bars of the frame thatsupports the rear or casterewheel aXle is also shown. Fig. t shows theplow bottom lowered tile Fig. 5 shows it raised. ig. 6 is a detailshowin the means employed for exerting a t and the de- J h on theplow-beam near its rear 1nd at a point over i the plow-beam, theplow-beam itself being in sectionthe section being taken at line 66 ofFig. 4. Fig. 7 is a detail, partly in section, of a portion of thetoothed segment and the lower end or socket portion of the operatinglever, and parts connected therewith. Big. 8 is a detail, partly inelevation and partly in vertical section, of the means for effecting thelocking and unlocking of the rear axle, and Fig. 9 is a detail of theadjust able plate upon the inclined upper edge of which the bearingblock carried by the plowbeam rests.

In the several figures of the drawings in which corresponding parts areindicated by the same reference characters,-A indicates the plow-beam,at the forward end of which is pivotally attached a clevis (L, as usual,and B indicates an arched axle, of the usual construction, upon the endportions of which are journaled the main carrying wheels B-B.

6 indicates the plow bottom, secured to the plow beam A in the usualmanner.

CC indicate two similar bars, pivotally connected to two brackets c-c,that are bolted to and project from opposite sides of the plow-beam A,as shown in Fig. 3. These bars extend toward the rear of the machine,and between their rear enos is bolted a casting D, the rear end of whichis an enlarged tubular portion d, in which is rotatably mounted theupper end of an axle E that carries at its lower end suitable spindleson which are journaled caster-wheels ee.

F is a block bolted to one side of the plowbeam A, which block asclearly shown in Fig. 3, extends over the top of the plowbeam, and is atits rear end sufliciently wider than the plow-beam to come in contactwith the inner faces of the rearwardly converging bars CC, thus actingto pre vent any lateral swing of such side bars and the mechanismcarried thereby. This block F at one of its rear upper corners has a lateral projection f that will, when the plow proper is in its lowermostposition, rest upon the upper inclined edge of another and smaller blockG, which is bolted to one of the side bars C. This second mentionedblock G is provided with a slot g, as shown in Fig. 9, which enables itto be adjusted forward or back as desired, and accordingly .s suchadjustment is made the depth to \ahich the plow bottom can enter theground will be regulated, thus affording a simple mechanism for changingthe set or suction of the plow.

H indicates a segmental rack bolted to one of the bars C. The lowerportion of this rack has formed with it a laterally projecting sleeve(see Fig. 7) in which there is a hub 72, formed with a socket member Iof the operating hand lever, the other or handle portion of such leverbeing indicated by I. The operating lever thus turns freely on its hubh. One end of the hub h is squared as indicated at i and upon thissquare end is mounted a short arm i which is thus caused to turn withthe turning of the hub 72/. At the opposite end of the hub it there isloosely journaled a short foot lever J which is not affected by themovement of the operating hand lever until such hand lever has beenturned back into position far enough to cause the pin 3' to abut againstit. The parts carried by the hub h are held in position by the bolt 7".

K is an arm secured rigidly to the arched axle B to the upper end ofwhich arm is pivoted the forward end of a link 7c, the rear end of suchlink being pivotally connected to the socket member I of the operatinglever.

L indicates a rod, the forward end of which is suitably secured to thefoot lever J, and the rear end of which is hooked into or otherwisesecured to the lower end of the bell-crank lever Z that is pivoted in arecess 1 in the bracket D that is secured between the rear ends of thebars CC. In the construction shown the pivot for this bell-crank lever Zis formed by one of the bolts used for attaching the bracket D in place.The lower end of this bell-crank lever has formed in it a rearwardlyextending tooth m adapted to enter a notch m that is formed in theforward end of the arm M that is clamped to the axle E below the headportion d of the bracket D. The tooth m is normally held in the notch mby a coiled sprin 12..

With the machine in operation and with the parts in the positionindicated in Fig. 1, wherein the plow bottom is shown in its lowermostposition, the caster-wheels ee will be held rigidly in position so as tofollow in a direct line behind the plow by reason of the fact that theirsupporting side bars CC are prevented from any sidewise motion by reasonof contact of their inner faces with the sides of the large block F thatis bolted to and overlies the plow-beam A. If the suction of the plowbottom needs to be changed slightly at any time that can be readilyeffected by loosening the nut on the bolt that holds the smaller blockG, carried by one of the side bars 0, and adjusting such block backwardor forward as may be required, and by reason of the upper edge of thisblock being inclined, it is apparent that the plow bottom will be set asrequired. When it is desired to raise the plow out of the ground, apulling back on the hand-lever I will of course effect this through thepull exerted by the link 76 and bracket K on the arched axle, as will bewell understood. the raising of the plow beam through this movement ofthe arched axle, an additional lift will be given to the rear portion ofthe plow beam at a point over the plow bottom by reason of the turningof the short arm i which, as stated, is fast on the squared end i of thehub h of the lever. The end of this arm during the raising movementcomes in contact with the turned upper end of a heavy plate N, that isbolted to one of the faces of the plow-beam A. By this arrangement ofparts, the same movement of the operating lever that turns the archedaxle causes the raising of the plow-beam near its forward end and alsocauses a direct lift on such plow-beam directly over the plow bottom,and hence causes such plow bottom to rise evenly out of the ground andbe sup ported when raised in a position above the ground practicallysimilar to that occupied by it when in the ground. By thus elevating theplow bottom, ample clearance is afforded in transporting the machinefrom place to place. W hen turning the machine at the end of a furrow,the caster-wheels can be allowed to turn freely as is necessary by theoperator pressing on the foot lever J, which foot lever, as stated,swings independently on the hub h, and this movement through the rod Lwill, as will be readily understood, draw the tooth m forward out of thenotch m which of course acts to permit the axle E that carries thecaster-wheels to freely turn. During this act of turning, the plowbottom need not be and generally will not be raised out of the ground.When, however, the plow bottom is raised to its highest point so as toplace it in proper posi- In addition to tion for transportation fromplace to place,

as shown in Fig. 2, the act of turning it into this position will alsocause the release of the locking engagement between the tooth m and thenotch m, due to the fact that the pin j at the lower end of theoperating lever will strike against the rear edge of the foot lever J,and move it forward in the same manner that it would be moved forward bythe operators foot. Thus it will be seen that the caster-wheels can bereleased so as to turn independently, either by foot pressure, while theplow bottom is in its lower position, or automatically, during theraising of the plow.
